Expression Encoder 4 SDK在直播時拋出DCOM錯誤

Question

我試圖將音頻和視頻直播從我的電腦傳輸到託管服務上的發佈點。我已經編寫了我認爲應該有的所有代碼（目前只是在小型控制檯應用程序中測試代碼）。代碼本身不會拋出錯誤，它運行得很好，視頻從我的網絡攝像機中被拉出，但是當試圖發送流到發佈點時，系統事件日誌中出現DCOM錯誤「DCOM無法與計算機通信streamwebtown.com使用任何已配置的協議。「 我嘗試使用SDK附帶的實際表達式編碼器4客戶端應用程序來執行相同的操作，並且視頻/音頻饋送對相同的發佈點工作正常。 我在互聯網上搜索了很多，看看是否有其他人遇到了這個問題，但卻空了。詢問社區是否有任何想法？從應用

代碼：

static void Main(string[] args) 
{ 
    EncoderDevice video = EncoderDevices.FindDevices(EncoderDeviceType.Video).Count > 0 ? EncoderDevices.FindDevices(EncoderDeviceType.Video)[0] : null; 
    EncoderDevice audio = EncoderDevices.FindDevices(EncoderDeviceType.Audio).Count > 0 ? EncoderDevices.FindDevices(EncoderDeviceType.Audio)[0] : null; 
    LiveJob job = new LiveJob(); 
    if (video != null && audio != null) 
    { 
     LiveDeviceSource source = job.AddDeviceSource(video, audio); 
     job.ActivateSource(source); 
     PushBroadcastPublishFormat publishingPoint = new PushBroadcastPublishFormat(); 
     publishingPoint.PublishingPoint = new Uri("http://streamwebtown.com/abc"); 
     publishingPoint.UserName = "user"; 
     publishingPoint.Password = PullPW("Stream"); 
     job.ApplyPreset(LivePresets.VC1Broadband16x9); 
     job.PublishFormats.Add(publishingPoint); 
     job.StartEncoding(); 

     Console.ReadKey(); 
     job.StopEncoding(); 
    } 
} 

private static SecureString PullPW(string pw) 
{ 
    SecureString s = new SecureString(); 
    foreach (char c in pw) s.AppendChar(c); 
    return s; 
}

我已經找到了答案，這不是驗證對服務器的。所以改變了我的代碼到下面，它突然工作得很好。

static void Main(string[] args) 
     {
 
      EncoderDevice video = EncoderDevices.FindDevices(EncoderDeviceType.Video).Count > 0 ? EncoderDevices.FindDevices(EncoderDeviceType.Video)[0] : null; 
      EncoderDevice audio = EncoderDevices.FindDevices(EncoderDeviceType.Audio).Count > 0 ? EncoderDevices.FindDevices(EncoderDeviceType.Audio)[0] : null; 
      LiveJob job = new LiveJob(); 
      job.AcquireCredentials += new EventHandler(job_AcquireCredentials); 
      if (video != null && audio != null) 
      { 
       LiveDeviceSource source = job.AddDeviceSource(video, audio); 
       job.ActivateSource(source); 
       PushBroadcastPublishFormat publishingPoint = new PushBroadcastPublishFormat(); 
       publishingPoint.PublishingPoint = new Uri("http://streamwebtown.com/abc");
 

  WindowsMediaOutputFormat wmof = new WindowsMediaOutputFormat(); 
      VideoProfile vProfile = new AdvancedVC1VideoProfile(); 
      AudioProfile aProfile = new WmaAudioProfile(); 
      wmof.VideoProfile = vProfile; 
      wmof.AudioProfile = aProfile; 

      job.ApplyPreset(LivePresets.VC1Broadband16x9); 
      job.PublishFormats.Add(publishingPoint); 
      job.OutputFormat = wmof; 
      job.PreConnectPublishingPoint(); 
      job.StartEncoding(); 
      //After finished encoding dispose of all objects. 
      Console.ReadKey(); 
      job.StopEncoding(); 
      job.Dispose(); 
      video.Dispose(); 
      audio.Dispose(); 
      source.Dispose(); 
     } 
    } 

    static void job_AcquireCredentials(object sender, AcquireCredentialsEventArgs e) 
    { 
     e.UserName = "user"; 
     e.Password = PullPW("Stream"); 
     e.Modes = AcquireCredentialModes.None; 
    } 

    private static SecureString PullPW(string pw) 
    { 
     SecureString s = new SecureString(); 
     foreach (char c in pw) s.AppendChar(c); 
     return s; 
    }
